Categorised as an essential store by the government, B&M has been open throughout the lockdown.
Shoppers can buy tinned and dried foods, as well as toiletries and cleaning products.
As well as essential items, the popular retail is also selling its Christmas decorations and foods ranges.
And one of its latest treats is proving to be so popular that fans are refusing to share it with their friends and family.
B&M is now selling a Viennetta biscuit caramel flavour ice cream for just £1, the Liverpool Echo reports.
On social media, the store wrote: "We've been loving caramel flavours all year and this #Viennetta sounds like it might be our favourite version yet. For just £1, it's 65ml of stunning ice cream; and available in both B&M and @HeronFoods. WHO's going to try this!?"
The post attracted more than 7,000 likes and hundreds of comments including Instagram users tagging friends to make them aware of the item too.
Among the comments, users claim they "need" the ice cream whilst others said it reminded them of when they were younger when the item was first released.
Other comments included one user writing: "Wow! Vienetta and Caramel! My two fave things."
Another said: "Oh my! W love a bit of vienetta!! Will have to try this!! Xx"
A third added: "Omg say what? I need now"
A fourth said: "Omg this sounds amazing"
And, a fifth user appeared to be upset at the prospect of having to share with a friend, tagging the friend, the user said: "If I'd have known this before I went b&m today you know there would have been 2 in my trolley one for you n one for me"
B&M replied to this comment and said: "You'll have to share now"
